<P>PROBLEM TO BE SOLVED: To provide a treatment method for an organic waste realizing reduction of treatment cost of a dehydration cake and totally realizing low running cost by effective utilization of a gas such as hydrogen, oxygen and chlorine generated by an additional facility therefor, and its system. <P>SOLUTION: Moisture content in the dehydration cake 13 obtained by dehydrating/treating the waste treatment liquid 10 by a dehydration machine 11 is electrolyzed in an electrolysis tank 16. The oxygen 18 generated on an anode of the electrolysis tank is used for aeration of a waste treatment facility 9 to enhance efficiency of denitrification from the waste liquid. Further, the chlorine 19 is introduced into a sterilization tank 22 so as to sterilize the waste liquid from the dehydration machine 11. Whereas, the hydrogen 23 generation on a cathode of the electrolysis tank 16 is once fed to a methane gas holder 4 and is introduced, for example, to a generator 5 such as fuel battery as a fuel gas 24 comprising methane + hydrogen together with methane 3 to realize energy-saving. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
